Carotid Body Tumorの1例

Carotid Body Tumor

　頸動脈毬腫瘍は比較的稀な疾患で現在までに欧米で約400例，本邦では約10数例の報告をみるに過ぎない。

　本症の治療として外科的摘出以外に方法はないが，腫瘍のみを完全に剔出しえたものは手術例の約50％で，残りのものは頸動脈分岐部と共に切除するか或は手術不能となつている。

A case of the carotid body tumor in a 23-year-old female is described. The tumor is known to have existed for at least three years before surgical treatment was perfor-med in our clinic. From the operative fin-dings the neoplastic tissue was found to be closely adherent to the wall of the carotid arteries but the tumor was completely extir-pated without ligation of the arteries.

The histopathologic changes exhibited the typical structure of carotid body tumor, and the chromaffin cells were successfully demo-nstrated in the tissue.
